The short answer
These bikes answer different questions, so the verdict is a question: does your route contain something a single rear hub motor and 720Wh will struggle with? If not, buy the EB26 — it does the job for $669, arrives Class 3 compliant, ships 90% assembled, carries the UL 2849 claim and rolls more calmly than any 20-inch bike here. If yes, buy the S8 and do not compromise, because a cheaper bike bought for that terrain gets replaced, and replacement costs more than $380.
These are the calmest bike AMYET sell and the most capable one, $380 apart. Almost nobody arrives here by accident. Shoppers usually reach it one of two ways.
The first is someone who started at the EB26 on price and then thought harder about their route — a long climb on the way home, a gravel section, a stretch of sand or winter slush — and realised a single 1000W hub motor and 720Wh might not be enough for it. The second is someone who started at the S8 because it looks like the best bike, and is now checking whether they can talk themselves down $380.
Those two people need different answers, so it is worth being direct: this is not a value comparison. The bikes are not competing for the same job. One is a commuter that happens to have fat tires; the other is a terrain bike that happens to be street-legal-ish. If you cannot say which job you have, start with our how to choose an electric bike guide instead of this page.
Price: $380 between the ends of the range
AMYET lists the EB26 at $669, down from $799, and the S8 at $1,049, down from $1,599. The S8 costs about 57% more. For context, the middle bike of the five, the G60, is $689. The EB26 and G60 sit twenty dollars apart; the S8 sits a long way above both, at about half as much again as the G60 rather than more than the two of them combined, which would be $689 + $669 = $1,358. That shape tells you something: the G60 and the EB26 are variations on one idea, and the S8 is a different idea altogether.
$0.93 vs $0.87
price per nominal watt-hour
$669 ÷ 720Wh ≈ $0.93 for the EB26. $1,049 ÷ 1200Wh ≈ $0.87 for the S8. The expensive bike is the better buy on stored energy per dollar — one of the few places in this comparison where the S8 is cheaper rather than dearer.
That figure is worth sitting with, because it undercuts the usual assumption that the budget bike is the value pick. On battery alone the S8 is better value than the EB26, and it also carries a second motor, hydraulic brakes and full suspension. The EB26's claim on your money is not efficiency; it is that it costs $380 less in absolute terms, which is the only currency that matters if the $380 does not exist. Both numbers stay remarkable against the rest of the field: the VTUVIA SF20H works out at $1,399 ÷ 672Wh ≈ $2.08 per watt-hour and the EUNORAU SPECTER-S 3.0 at $2,999 ÷ 840Wh ≈ $3.57.
Battery: 720Wh against 1200Wh
The EB26 carries a 48V 15Ah pack, which is 720Wh. The S8 carries 48V 25Ah, or 1200Wh — 67% more stored energy, the largest capacity gap between any two bikes in the range.
AMYET states about 30 miles on throttle alone and up to 60 miles on pedal assist for the EB26, which is an unusually transparent way to publish range. For the S8 they claim 70 to 75 miles maximum; run that backwards and 1200Wh ÷ 75 miles = 16Wh per mile, which means a light rider, low assist, flat ground and almost certainly not both motors working. The arithmetic matters more than either claim:
EB26, moderate pedal assist on road, about 25Wh per mile: 720Wh ÷ 25 ≈ 29 miles. An estimate.
EB26, throttle-heavy, about 24Wh per mile: 720Wh ÷ 24 = 30 miles — consistent with AMYET's own throttle-only figure, which suggests their number is honest.
S8 with both motors on rough ground, about 40Wh per mile: 1200Wh ÷ 40 = 30 miles. Also an estimate, and roughly the same distance as the EB26 despite 67% more battery.
67% more battery
for roughly the same planning distance
That last line is the one to remember. Two motors, more weight and harder terrain consume the capacity advantage. The S8's bigger pack is not there to give you more miles; it is there to stop the second motor from taking miles away. If pure distance per dollar is your goal, neither of these is the pick — the G60's 960Wh at $689 is, and our G60 vs EB26 comparison explains why.
Two practical notes. The EB26's battery is listed as IP65 rated, a specific water-ingress claim on the pack; the S8 is listed as IP54 for the bike. Charge time on the EB26 is stated as 5 to 8 hours, and AMYET publishes no charge time for the S8, only that it supports dual charging. For the full method behind these estimates, see our battery and range guide.
One rear motor against all-wheel drive
The EB26 uses a 1000W rated brushless rear hub motor with a claimed 1500W peak. The S8 uses two 1000W motors, 2000W rated combined with a claimed 3000W combined peak, driving both wheels. Rated power is what a motor sustains without overheating; peak is a short-burst figure for pulling away or cresting a rise. Both bikes claim the same peak per motor, so the S8's advantage is not that its motors are stronger. It is that there are two of them, on two different wheels.
Why a driven front wheel changes things
A rear hub motor puts all its effort through one contact patch. On dry tarmac that is fine, because grip is not the limit. On loose gravel, sand, snow or wet grass it is very much the limit: the rear wheel breaks traction, the motor spins uselessly, and the bike stops climbing. Splitting the effort across two wheels asks less grip of each tire, which is why all-wheel drive transforms loose-surface and steep riding while doing almost nothing on a smooth road.
On a long climb there is a second effect. A single hub motor asked to sustain full output for several minutes gets hot, and controllers cut power to protect it. Sharing the load between two motors keeps each cooler. Neither listing gives thermal data, so this is mechanism rather than measurement — but it is the mechanism behind why dual-motor bikes hold speed on gradients where single-motor bikes fade.
Both bikes have a 7-speed drivetrain, which on hub-motor bikes matters mainly because it lets you contribute your own 150W or so on a climb, reducing motor heat. Our single vs dual motor guide and e-bike for hills guide cover the decision in full.
Wheels, suspension and how each one rides
This is the one area where the cheaper bike has an argument the expensive one cannot answer.
The EB26 runs 26 × 4-inch tires; the S8 runs 20 × 4-inch. Both have the same 4-inch air volume, which is what makes fat bikes forgiving over potholes and gravel, but diameter is not interchangeable. A 26-inch wheel meets an obstacle at a shallower angle, climbs out of it rather than dropping in, and loses less momentum doing so. Over a long stretch of broken tarmac the bigger wheel is simply calmer. It also suits taller riders better, since a 20-inch fat bike can feel small under a long frame.
The S8 answers with architecture rather than diameter: AMYET lists it as full suspension, against the EB26's lockable aluminium dual shock absorbers. Those are different solutions to different problems. Full suspension keeps a wheel in contact with an uneven surface, which is a traction requirement on trail. Lockable shocks let you firm the bike up for smooth road, which stops it bobbing under pedalling effort and wasting energy — a commuting requirement.
Neither listing publishes travel, damping type or adjustability, so the quality of either system cannot be judged from the specification sheets. At the EB26's price, budget coil forks with minimal damping are the category norm; assume the tires do most of the work. Our 20 vs 26 inch guide and fat-tire guide go further into both. The frames differ too: AMYET lists high-carbon steel for the EB26 — more forgiving over rough ground and cheaper to repair than aluminium, but heavier — and a full-suspension fat-tire frame for the S8.
Brakes, certification and the trade nobody mentions
The EB26 has dual mechanical disc brakes. The S8 has hydraulic discs. This is a straightforward win for the S8, and on the heavier, faster, hill-oriented bike it is a necessity rather than a luxury. Mechanical discs pull the pad through a cable: softer lever feel, braking force dependent on hand strength, and cable stretch that needs adjusting out as the system beds in. Hydraulic discs self-adjust, need far less hand force, and modulate better on a long descent when your hands are tired.
Where the cheaper bike wins
Certification. AMYET states that the EB26 complies with UL 2849 and lists an IP65 battery. The same UL 2849 claim does not appear on the S8 listing. To be exact, it is not published for the S8. That is not evidence the bike is uncertified and we will not report it as such. But UL 2849 covers the complete electrical system rather than the pack alone, and several US cities, building managers and insurers now require it before a bike may be stored or charged indoors. A buyer who needs that documentation has it for the EB26 and does not have it for the S8, and should ask AMYET directly. For a $669 bike to hold a safety claim that a $1,049 bike's listing does not is worth flagging plainly, particularly for apartment dwellers.
Speed, weight, assembly and the law
AMYET claims up to 28 MPH for the EB26. For the S8 they quote up to 32 MPH in some places and up to 35 MPH in others; we use the lower, more consistently published figure and flag the inconsistency rather than picking the flattering one.
That gap is a legal distinction, not just a performance one. Around forty US states use a three-class framework in which Class 3 is pedal assist to 28 MPH. The EB26 lands exactly on that line. The S8, at either published figure, sits above it — outside all three classes in those states, which can mean it is not legally an e-bike there. Most bikes in this category ship with a configurable speed limit in the display, but the EB26 arrives compliant and the S8 does not. Expect shared-path rules to be stricter than road rules.
On weight, AMYET publishes no bare bike weight for either model. The only EB26 figure available is a 30 kg — about 66 lb — shipping weight, which includes packaging, so the bike itself is lighter by an unstated amount. For the S8 there is nothing at all, though a second motor, a 1200Wh pack and full suspension make it clearly the heavier machine. Neither number is good enough to plan a car rack around, and it is worth knowing that eleven of the seventeen non-AMYET bikes we cover publish a real bike weight, from 39 lb to approximately 110 lb.
Assembly is a real cost difference. The EB26 ships 90% assembled with a toolkit, manual and key. For the S8, AMYET recommends professional installation — reasonable for a full-suspension dual-motor bike with hydraulic brakes, and an expense on top of the $380. Both carry a one-year warranty, a 30-day risk-free trial and a 330 lb payload rating; our guide for heavier riders explains what that rating does and does not cover.
Common questions
Is the S8 worth $380 more than the EB26?+
Only if your terrain asks for it. The $380 buys a second 1000W motor driving the front wheel, 480 extra watt-hours, hydraulic rather than mechanical disc brakes, and full suspension. On sustained climbs, sand, snow or loose gravel those change how the bike behaves fundamentally. On a road commute they add weight and cost for capability you never use, and the EB26 rolls more comfortably on its 26-inch wheels. Note also that AMYET recommends professional installation for the S8, which is a further cost on top of the price gap.
Does the S8’s 1200Wh battery mean much more range than the EB26?+
Less than the numbers suggest. The S8 holds 67% more energy, but it feeds two motors on a heavier bike. At a rough 40 watt-hours per mile with both motors working on loose ground, 1200Wh ÷ 40 = about 30 miles, an estimate. The EB26 at around 24Wh per mile on throttle gives 720Wh ÷ 24 = about 30 miles, which matches AMYET’s own throttle-only claim. Ridden gently on flat ground the S8 goes considerably further, but that is riding a dual-motor bike is not needed for.
Which one is legal to ride at its top speed?+
The EB26 is the easier of the two to place. AMYET claims up to 28 MPH for it, which is exactly the Class 3 ceiling under the three-class framework around forty US states use. The S8 is quoted at up to 32 MPH in some AMYET material and up to 35 MPH in others, and either figure sits outside all three classes in those states — potentially meaning it is not legally an e-bike there. Most bikes in this category have a configurable speed limit in the display. Check your local and shared-path rules before buying.
Why does the cheaper bike have the safety certification?+
AMYET states UL 2849 compliance for the EB26 and lists an IP65 battery. The same UL 2849 claim does not appear on the S8 listing. That is a gap in published information rather than evidence the S8 is uncertified, and we do not report it as one. UL 2849 covers the complete e-bike electrical system rather than the cells alone, and some US cities, building managers and insurers now require it for indoor storage or charging. If that applies where you live, ask AMYET directly before ordering the S8.
Should I just buy the G60 instead?+
For a lot of people, yes. At $689 the G60 sits $20 above the EB26 and $360 below the S8, and carries 960Wh — a third more than the EB26 and 20% less than the S8. It is the range pick of the three, and on 20-inch wheels it is the easiest to store. What it does not give you is the EB26’s 26-inch rolling comfort or the S8’s second motor, hydraulic brakes and full suspension. If your problem is distance rather than terrain or comfort, the G60 solves it most cheaply.
How do these two look next to VTUVIA and EUNORAU?+
On stored energy per dollar they win easily: $0.93 and $0.87 per watt-hour against $2.08 to $4.46 for the seventeen non-AMYET bikes we cover. On documentation they lose just as clearly. Neither publishes a torque figure, an assist sensor type or a bike weight, where sixteen of those seventeen publish torque of 40 to 220 Nm, eleven publish a weight and thirteen state a sensor type. That is the trade this whole site keeps coming back to, and it is a trade rather than a defeat.
